This is obviously a bit of a trick question in as much as, of course, 3C Multi-Use is an all-in-one product but alas, there are several similar products on the market that are primarily marketed as one or the other, which then can, in turn, be used for the other type of task. Our aim with this material was to create a toolbox favourite for many applications in a range of RAL colours that are most suited to common shades used in construction and decorating trends. The result is a true DIY legend and a very useful and effective professional tradespersons goto snagging list workhorse!
Yes it's a great choice for outside use. Unlike other all-in-one adhesive & sealant products on the market, 3C Multi-Use was designed as a true all-rounder and so, we opted for an anti-mould additive to cope with bonding & sealing internally in areas of high humidity, making it a superb inside snagger for multiple jobs, but with it's rugged final cure and excellent flexibility, Multi-Use is equally capable of dealing with UV and adverse weathering, making it a perfect fixer & sealer for most external construction applications also.
Although not a traditional grip (or grab) adhesive, 3C Multi-Use is a great performer when not comes to quick initial grab on light work jobs such as skirting boards and UPVC extrusions etc. The nasty chemicals used in old fashioned grip (grab) adhesives were and often still are very effective in use but also very volatile in nature for both the user and the environment and are fast becoming extinct in the marketplace due to this fact! Hybrid polymer adhesives are now used widely across many trades and have become just as popular for DIY use also. In the video we made, we used Multi-Use to stick a block of timber to our warehouse floor to act a stopper for the forklift truck, it grabbed the surface very well and it is still there in place to this day (over 2 x years later as of March 21) See it here.
As with silicone sealants, when using a material to bond or seal natural stone, a risk of staining or leeching as its known, is always present. Basically, in a nutshell, the plasticisers and oils used in many popular sealant products to cure the material tends to bleed from the main substance when extruded wet and cause unsightly staining on most natural stone surfaces as it cures. 3C Multi-Use as we've mentioned previously, was developed to be a true all-rounder and thus was formulated to have a non-staining cure system making it ideal for using to both bond and seal all natural stones.
